CROSS-REFERENCE TO RELATED APPLICATION

This application claims benefit of U.S. Patent Application No. 62/925,596, filed on Oct. 24, 2019; and U.S. Patent Application No. 63/044,898, filed on Jun. 26, 2020, both of which are hereby incorporated by reference in their entirety.

BACKGROUND

RAF kinase functions in the Ras-Raf-MEK-ERK mitogen activated protein kinase (MAPK) pathway (also known as MAPK/ERK pathway) by phosphorylating and activating MEK. By altering the levels and activities of transcription factors, MAPK leads to altered transcription of genes that are important for the cell cycle. Deregulation of MAPK activity occurs frequently in tumors. Accordingly, therapies that target RAF kinase activity are desired for use in the treatment of cancer and other disorders characterized by aberrant MAPK/ERK pathway signaling.

The RAF Family of Kinases

The RAF kinases are a family of serine/thronine protein kinases constitute core components of the RAS-RAF-MEK-ERK mitogen activated protein kinase (MAPK) signalling cascade (also known as the MAPK/ERK pathway), a pathway that mediates signals from cell surface receptors to the nucleus to regulate cell growth, differentiation and survival. The RAF proteins are related to retroviral oncogenes and are structurally conserved from metazoans to mammals, as is the MAPK/ERK pathway. Their dysregulation leads to uncontrolled cellular proliferation, survival and dedifferentiation. Consequently, RAF kinases are altered or inappropriately activated in a majority of cancers.

The MAPK/ERK signalling pathway is a network of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell. The signal starts when a signaling molecule binds to the receptor on the cell surface and ends when the DNA in the nucleus expresses a protein and produces some change in the cell, such as cell division. The pathway includes many proteins, which communicate by adding phosphate groups to a neighboring protein, which acts as a molecular “on” or “off” switch, and overall the pathway can be divided into 3 steps: (i) Ras activation, (ii) a kinase signal transduction cascade, and (iii) regulation of translation and transcription. Briefly, an extracellular mitogen or a signaling molecule binds to the membrane receptor. This allows Ras (a small GTPase) to swap its GDP for a GTP and become active. Activated Ras activates the protein kinase activity of RAF kinase. RAF kinase phosphorylates and activates MEK (MEK1 and MEK2). MEK then phosphorylates and activates a MAPK (also known as ERK). MAPK activation regulates activities of several transcription factors and also alters the translation of mRNA to proteins. By altering the levels and activities of transcription factors, MAPK leads to altered transcription of genes that are important for the cell cycle.

There are three known mammalian RAF isoforms: C-RAF (also known as RAF-1, or c-RAF-1), B-RAF, and A-RAF. All RAF kinases share a common modular structure consisting of 3 conserved regions (CR1, CR2, and CR3) with distinct functions. CR1 contains (i) a Ras-binding domain (RBD), which is necessary for the interaction with Ras and with membrane phospholipids required for membrane recruitment, and (ii) a cysteine-rich domain (CRD), which is a secondary Ras-binding site and also necessary for the interaction of CR1 with the kinase domain for RAF autoinhibition. CR2 contains important inhibitory phosphorylation sites participating in the negative regulation of Ras binding and RAF activation. CR3 features the kinase domain, including the activation segment, whose phosphorylation is crucial for kinase activation.

Functionally, the RAF structure can be split into a regulatory N-terminal region, containing the RBD, which is critical for activation as well as inhibitory phosphorylation sites, and a catalytic C-terminal region, which includes phosphorylation sites necessary for the kinase activation. The regulatory domain restrains the activity of the kinase domain, and its removal results in constitutive oncogenic activation. However, the activity of the isolated C-RAF kinase domain is subjected to further regulation and can be stimulated by phorbol esters, v-Src, and phosphorylation.

The common and key step in the activation of all 3 RAF kinase isoforms is membrane recruitment by a Ras family protein. The RAF kinases are located in the cytosol in their inactive state when bound to 14-3-3 proteins. In the presence of active Ras, they translocate to the plasma membrane. Membrane translocation triggers further activation events, such as the binding of PP2A to dephosphorylate the inhibitory pS259 site in RAF-1 (and presumably the corresponding sites in A-RAF and B-RAF) and the co-localization with the kinases responsible for the multiple activating phosphorylations. The sequences forming the binding interface are well conserved in the RAF as well as Ras family indicating that several members of the Ras family have the ability to bind RAF kinases. H-Ras, N-Ras, and K-Ras stimulate all 3 RAF isoforms and are the only Ras proteins that activate B-RAF. In contrast, A-RAF is also activated by R-Ras3, while C-RAF responds weakly to R-Ras3, Rit, and TC21 as well. But, all RAF kinases share MEK1/2 kinases as substrates. MEK1/2 in turn activate ERK1/2, and this pathway regulates many cellular functions such as cell proliferation, differentiation, migration, or apoptosis.

C-RAF

C-RAF was first to be identified and is a ubiquitously expressed isoform. In humans, C-RAF is encoded by the RAF1 gene. C-RAF also has a known splice variant preferentially expressed in the muscle and brain. C-RAF plays a critical role in mediating the cellular effects of growth factor signals. In the inactive state, C-RAF exists in a closed conformation in which the N-terminal regulatory region folds over and occludes the catalytic region. This conformation is stabilized by a 14-3-3 dimer binding to an N-terminal site, phospho-S259 (pS259), and a C-terminal site, pS621. Dephosphorylation of pS259 at the cell membrane by specific phosphatases (PP2A, PP1) releases 14-3-3 from its N-terminal binding site in C-RAF, thereby allowing conformational changes to occur that unmask the RBD and CRD domains in the CR1 region to enable Ras binding and membrane recruitment.

B-RAF

B-RAF is encoded in humans by the BRAF gene, also known as proto-oncogene B-RAF and v-RAF murine sarcoma viral oncogene homolog B. Alternative splicing gives rise to multiple B-RAF isoforms which are differentially expressed in various tissues. Whereas activation of A-RAF and C-RAF requires both phosphorylation and dephosphorylation of certain residues, as well as binding to other proteins, B-RAF becomes activated immediately upon translocation to the plasma membrane. B-RAF exhibits higher basal kinase activity than A-RAF and C-RAF. B-RAF requires Ras and 14-3-3 binding for its activation and is inhibited or activated by PKA depending on the levels of 14-3-3 expression, which need to be high for permitting activation. B-RAF activity is also regulated by splicing. B-RAF isoforms containing exon 8b are more phosphorylated on the inhibitory S365 site, leading to an increased interaction with 14-3-3 and strengthening the inhibitory interaction between N-terminal regulatory domain and kinase domain, altogether resulting in lower kinase activity.

A-RAF

Serine/threonine-protein kinase A-RAF or A-RAF is an enzyme encoded by the ARAF gene in humans. There are 2 known splice isoforms of A-RAF-DA-RAF1 and D-RAF2. They lack the kinase domain and act as dominant inhibitory mutants of Ras and ARF GTPases. DA-RAF1 is a positive regulator of myogenic differentiation by mediating the inhibition of the ERK pathway required for differentiation. There are several ways A-RAF is different from the other RAF kinases. A-RAF is the only steroid hormone-regulated Raf isoform. In addition, the A-RAFprotein has amino acid substitutions in a negatively charged region upstream of the kinase domain (N-region), which contributes to its low basal activity. A-RAF is also only weakly activated by oncogenic H-Ras and Src and also displays low kinase activity towards MEK (the lowest kinase activity towards MEK proteins in the Raf kinase family). In addition to phosphorylating MEK, A-RAF also inhibits MST2, a tumor suppressor and pro-apoptotic kinase not found in the MAPK pathway. By inhibiting MST2, A-RAF prevents apoptosis from occurring. However, this inhibition is only occurs when the splice factor heterogenous nuclear ribonucleoprotein H (hnRNP H) maintains the expression of a full-length A-RAF protein. Tumorous cells often overexpress hnRNP H which leads to full-length expression of A-Raf which then inhibits apoptosis, allowing cancerous cells that should be destroyed to stay alive. A-RAF also binds to pyruvate kinase M2 (PKM2), again outside the MAPK pathway. PKM2 is an isozyme of pyruvate kinase that is responsible for the Warburg effect in cancer cells. A-RAF upregulates the activity of PKM2 by promoting a conformational change in PKM2. This causes PKM2 to transition from its low-activity dimeric form to a highly active tetrameric form. This causes more glucose carbons to be converted to pyruvate and lactate, producing energy for the cell, linking A-Raf to energy metabolism regulation and cell transformation, both of which are very important in tumorigenesis.

RAF Kinase Inhibitors

Aberrant activation of the MAPK/ERK pathway is frequently found in various cancers and is a target for cancer therapeutics. In particular, B-RAF has emerged as one of the most attractive molecular targets for cancer therapeutics because somatic mutations of B-RAF have frequently been found in human tumors. Approximately 20% of all cancer samples tested to date harbor mutations in B-RAF. B-RAF-V600E, a missense mutation in the kinase domain generated by the substitution of glutamic acid with valine at position 600 is the most common B-RAF mutation. C-RAF is mutated in ˜1% of the various tumor types tested and the rate of mutations in A-RAF is even lower. B-RAF and C-RAF form both homo- and heterodimers as part of their activation mechanism and A-RAF stabilizes the B-RAF:C-RAF complexes to sustain signaling efficiency. Also, it is C-RAF, not B-RAF, that transmits signals from oncogenic RAS to MEK. Therefore, in different contexts, each of the RAF isoforms act as a potential therapeutic target.

Sorafenib was the first RAF inhibitor to enter clinical trials. Sorafenib is a broad specificity drug that inhibits additional kinases, including vascular endothelial growth factor receptor family (VEGFR-2 and VEGFR-3), platelet-derived growth factor receptor family (PDGFR-b and KIT) and FLT3. Clinical trials showed no correlation between the clinical responses with B-RAF mutation status, indicating it is a poor inhibitor of B-RAF. This led to the development of a new generation of B-RAF inhibitors, including, but not limited to vemurafenib, SB-590885, and dabrafenib (GSK2118436). Although the initial results of the clinical studies in B-RAF-mutant melanoma were encouraging, as clinical testing began in other B-RAF-mutated cancers (such as thyroid and colorectal cancers) it became apparent that tumors of different cell types harboring B-RAF mutations responded differently to selective B-RAF inhibition. Moreover, the existence of both primary and secondary resistance to RAF inhibition poses as one of the greatest challenges to the progress of RAF kinase inhibitor therapy. The mechanisms of resistance fall into two broad categories. Intrinsic/primary resistance is displayed by approximately 50% of patients. The other 50% of the patients initially respond (>30% tumor shrinkage) to RAF inhibitor but subsequently develop progressive disease associated with acquired/secondary resistance to RAF inhibitor. These two categories are not mutually exclusive because nearly all responders have remaining disease and, thus, may display intrinsic resistance. The determinants of primary RAF inhibitor resistance seem to vary with tumor type, with alteration in RTK signaling also being involved. Potential mechanisms of secondary B-RAF inhibitor resistance include, but are not limited to, reactivation of ERK1/2 pathways, upregulation of RTK signaling, the upregulation of receptor tyrosine kinases, mutations in RAS, and upregulation of COT. B-Raf alternative splicing and amplification of B-RAF-V600E have also been implicated in ˜30 and 20% of patients, respectively. Moreover, RAF kinase inhibitors cause paradoxical activation of the MAPK pathway, which, in some instances, leads to the development of secondary RAS mutation-driven malignancies. As such, there is a need in the field for new RAF kinase inhibitors that overcome the existing pitfalls and challenges posed by the current inhibitors.

II. Biological Evaluation

Enzymatic RAF1 Kinase Activity Determination

Small molecule inhibition of RAF1 kinases was measured using ADP-Glo assay. In the assay, ADP is converted to ATP in the presence of test kinase and substrate, resulting in luciferase reaction and luminescent readout with light generated proportional to the relative kinase activity. Compounds diluted in DMSO were used in 10-point, 3-fold dose curve for both assays. Final concentrations of 3 nM RAF1 (CarnaBio, Cat. 09-125) and 30 nM MEK1 substrate (Millipore, Cat. 14-420) were incubated with 3 μM ATP, 10 mM MgCl2, 0.003% Brij-35, 2 mM DTT, 0.05% BSA, 1 mM EGTA, and 50 mM HEPES for 90 minutes at room temp prior to addition of ADP-Glo reagent (Promega, Cat. V9102) for 40 minutes, and detection reagent for 45 minutes. Luminescence was read on an Envision plate reader (PerkinElmer) and percent remaining activity was used to calculate IC50 using a four-parameter fit model using Dotmatics Knowledge Solutions Studies curve fitting (Dotmatics, Bishops Stortford, UK, CM23). Representative data for exemplary compounds is presented in Table 2.
